Abstract
Induced travel is an important component of travel demand and increasing attention has been paid to building analytical model to get more precise travel demand forecasting. In general, induced demand can be defined in terms of additional trips that would be made if travel conditions improved (less congested, lower vehicle costs or tolls). In this paper the induced demand resulting from higher design speeds and, therefore by less travel time, for the High Speed 1 in UK will be modelled on the basis of the relationship between existing High Speed Rail demand (dependent variable) to existing High Speed Rail travel times and costs. The covariates include socioeconomic variables related to population and employment in the zones connected by the High Speed Rail services. This model has been calibrated by mean of a before and after study carried on the corridor, when the new High Speed Rail services was introduced. Elasticities of induced travel (trips and VMT) have been computed with respect to fares, travel time and service frequency.

Summary
Investments in High Speed Rail (HSR) systems are currently being undertaken in many countries around the world These systems represent a closer to optimal solution to meet challenges of increasing mobility demand while simultaneously addressing the greater attention of citizens to sustainability issues. As far as the authors know, concentrate on induced demand by HSR [2] It is well reported in the literature that induced demand is an important component of travel demand, and increasing attention has been paid to building analytical models to get more precise travel demand forecasting. In this paper the induced demand resulting from higher design speeds and, by less travel time, for High Speed 1 (HS1) in UK will be modelled.
